Application September 15, 1931, Serial No. 562,985. Renewed August 15,1933 1 Claim. (01. 126288) This invention relates to improvements infireplaces and has particular reference to a combined fireplace throatand damper.

The principal object of this invention is to produce a device of thischaracter whichis constructed of a blank, and so arranged that it may beemployed in connection with the average fireplace.

A further object is to produce a device which- Figure 2 is a perspective'view of the damper,

Figure 3 is a perspective view of the hood in which the damper ispositioned,

Figure 4 is a top plan view of the damper actuating mechanism,

Figure 5 is a side elevation of Figure 4, and

Figure 6 is a fragmentary detail view showing the manner in which thedamper is pivoted to the hood.

The ordinary fireplace permits the smoke to pass up the chimney at will,and provides no means whereby the draft up the chimney may becontrolled. Applicant has provided means whereby this draft maybecontrolled, and has from passing up the chimney from the room when thefireplace is out of use.

It is common in many apartments and houses to only occasionally use thefireplace, the customary heat being provided by means of registers orradiators, and it is therefore advantageous to V retain this heat in theroom.

Referring to the drawing in detail, it will be noted that my device isentirely concealed from the front of the fire place, and consists of ablank 5, which has turned-down side pieces 6 and a turned out lintel '7which supports the bricks'8, forming the upper portion of thefireplace,and

invention or the scope of the subjoined claim.

further provided a means for preventing heat' particularly that portionadjacent the throat to which is' pivotally secured a chain elementhaving a plurality of links capable of being bent This chain extendsthru a guide 16'secured to the blank 5 and having its forward end flushwith the face of the fireplace brick 8. A handle 17 is secured to thechain ele-. ment so as to extend beyond the face of the fire placebrick, as best illustrated in Fig. 1,v where it may be grasped and movedoutwardly or inwardly, to open or close the damper any given 5 amount.It will here be noted, that thru the use of this particular type ofchain, which can only be pivoted in one plane, that, when the chain ispulled out, oneor more links, each link, when hanging downwardly, willprevent the remaining links from pulling rearward movement, thus 7 size,shape and arrangement of parts may be resorted to withoutdeparting fromthe spirit of the Having thus described my invention, I claim:-- In adevice of the character described, the combination with a fire placehaving a throat, of a plate positioned in said fire place and adjacentsaid throat, said plate having down-turned side portions, a damperpivoted between said side portions, and when in a vertical position,being adapted to close said throat and remote means for actuating saiddamper, said remote means including an arm secured to said damper and alaterally rigid chain connected to said arm, said chain being capable ofmovement in one plane only, and extending to a point outside of saidfireplace.
